FIXED DNA MESSAGE (NEARLY). "Genomic DNA is like a word-processing document that is "read-only" with no changes possible, whereas the RNA is a transcript of the document that permits, and even requires, cutting and pasting to get to the final version." http://www.nature.com/scitable/topicpage/regulation-of-mrna-splicing-by-signal-transduction-14128469 View in LinkedIn

AMPLIFYING GENES. "Alternative splicing is one major mechanism that makes the most of the precursor messenger RNAs (pre-mRNAs) transcribed from these few genes by processing the pre-mRNA into a diverse array of mature mRNAs that encode distinct proteins." http://www.nature.com/scitable/topicpage/regulation-of-mrna-splicing-by-signal-transduction-14128469 View in LinkedIn

ONE MILLION PROTEINS, 21K GENES. "One gene can encode more than one protein (even up to 1,000). The human genome contains about 21,000 protein-encoding genes, but the total number of proteins in human cells is estimated to be between 250,000 to one million." No longer the one gene, one protein dogma. https://lnkd.in/dKXbSw4 View in LinkedIn

FRAGMENT FROM NATURE deals with the genetic phenomenon called alternative splicing. By this mechanism, organisms can significantly amplify the number of proteins at their disposal, with a relatively small number of genes, thus making these new proteins available for adaptation and new functions. This illustrates how nature has arrived at an ingenious solution to generate, once again, the many from the few. View in LinkedIn

DURABLE IMPLANTS. “Two monkeys with brain implants have steered wheelchairs using only their minds, researchers said Thursday, in another step forward for a field seeking to mobilize people with paralysis. And the brain implants that made the mind-to-computer interface possible have lasted in the monkeys for seven years.” https://lnkd.in/dQvunCh View in LinkedIn

MEDICAL USES. “BrainGate that allows fully paralyzed patients to control devices with their thoughts. BrainGate works by inserting a small chip, studded with about 100 needlelike wires—a high-tech brush—into the part of the neocortex controlling movement. These motor signals are fed to an external computer that decodes them and passes them along to external robotic devices.” http://www.wsj.com/articles/SB10001424052702304914904579435592981780528 View in LinkedIn
